You are just flat wrong and you seem determined to be wrong. State law clearly stated that schools HAVE to give parents the right and final say to opt their children out of materials they find offensive and let them know when those materials are to be presented so the parents can hold their children out of them. THE SCHOOL REFUSED TO DO THAT, and REFUSED TO GIVE THE PARKERS THE RIGHT TO OPT THEIR SON OUT OF THE GAY MATERIAL. It can't be made clearer than that. You are operating under a false sense of the facts at hand. The school violated the law. Period. The rest of your argument is flawed by your misinterpretation of that fact.
Absolutely. But that is not what happened. The school agreed to the request by Parker (see the emails). Then after the agreement, Parker asked for a meeting in which he raised his demand to any discussion at all. Of course, that was impossible to agree to, since a child might bring the subject up in class. Stopping the class or refusing a simple question until Parker could be contacted was out of the question.
THE SCHOOL REFUSED TO DO THAT, and REFUSED TO GIVE THE PARKERS THE RIGHT TO OPT THEIR SON OUT OF THE GAY MATERIAL. It can't be made clearer than that.
No, the school only did that after Parker was arrested and his trial. Then Parker filed a lawsuit, which was the proper course of action.
